Thanks so much f quick reply.
How about aspartate and glutamate that have high pKa at pH 7? And basically when the ASH and GLH naming being applied?
I should let you know that I previously sent the protein to a web-based software for pKa prediction.

A low pka would mean they are deprotonated at ph 7, so don't change them.
